‘Jumping Genes’ Are More Than Parasitic DNA

You might imagine that the DNA in your cells has a simple history. But that’s not the entire story. Nearly half of your genome is a wild drama, thanks to a genetic material called transposons that can clip itself out of the DNA sequence, float off, and paste itself somewhere else. While these “jumping genes” may seem pathological, they’re more than just junk. On this episode of The Quanta Podcast, host Hannah Waters speaks with writer Jake Buehler about these unruly genetic fragments and their connections to the evolution of everything from moths to wombs. This topic was covered in a recent story for Quanta Magazine. The audio coda this week is a piece of music called Transposon. It's a musical sonification of transposable elements from the human genome by composer and sound artist Sam Nester. He created it in collaboration with genomicist Stéphane Boissinot as part of a year-long artist-in-residence at the Center for Genomics and Systems Biology at NYU Abu Dhabi. Each week on The Quanta Podcast, Quanta Magazine editor-in-chief Samir Patel and Senior Editor Hannah Waters speak with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.
